Inventor fizz/e226. 6'2:

Attorneys Patented May 21, 1940 UNITED STATES PATENT OFFICE 5 Claims.

This invention appertains to new and useful improvements in means for measuring barrel hoops and more particularly to hoops that are to be re-used.

The principal object of the present invention is to provide an apparatus for substantially automatically measuring and cutting bands.

Another important object of the invention is to provide an attachment for barrel hoop cutting and punching machines whereby the hoops can be measured almost automatically, thus saving considerable time that is now consumed in measuring the bands before cutting and punching.

Other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a front elevational view of a cutting and punching machine showing the attachment in place.

Fig. 2 is a vertical sectional attachment.

Fig. 3 is a section on line 33 of Fig. 2.

Fig. 4 is a section on line 4-4 of Fig. 2.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to a conventional barrel hoop threading and punching machine such as is now on the market. This machine includes view through the a frame or case structure 6 to which the hoop measuring attachment generally referred to by numeral 1 is secured. This attachment 1 is secured in place in substantially the same plane with the cutters and punchers of the machine 5. The attachment 1 consists of the elongated substantially circular band 8 which at intervals has lugs 9 disposed outwardly from its edge portion to serve as guard means for the barrel hoop Ill. One end of the barrel hoop l0 isdisposed over the hook H and disposed under the band 3 and upwardly where it is disposed under the cutter where it is cut off at the proper length.

The hook H is disposed through a slide block I2 which is slidably disposed in the slot l3 of the band 8. The block 12 is partially secured to the hook I I by a pin or the like M. The shank of the hook II is threaded and extends through the block 12 and slot l3 and is equipped with laterally as at I8 and abuts the band8 at the same point at which oneend of the brace bar I9 abuts the band 8, thus acting as a brace. The upper portion of this leg I! has the opening 2|) therein for receiving a machine screw 2| which serves to attach one end portion of the band to the machine 5.

The other end of the band 8 is provided with a substantially horizontally disposed portion 22 having the opening 23 therein through which the securing element 24 is disposed and driven into the ledge 25 of the machine 5. Thus the band is firmly held in place and braced by the legs l8 and brace bar l9.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what claimed 1s:

1. A barrel hoop measuring attachment for cutting and punching machines comprising an annulus split and having its end portions attached to the machine and an adjustable barrel hoop engaging member on the band.

2. A barrel hoop measuring attachment for cutting and punching machines comprising an annulus split and having its end portions attached to the machine and an adjustable barrel hoop engaging member on the band, one end portion of the band being disposed inwardly and terminating to abut an intermediate portion of the band to form a brace.

3. A barrel hoop measuring attachment for cutting and punching machines comprising an annulus split and having its end portions attached to the machine and an adjustable barrel hoop engaging member on the band, one end portion of the band being disposed inwardly and intermating to abut an intermediate portion of the band to form a brace, and a cross brace having one end abutting the band at substantially the same point that the leg abuts the band.

4. A barrel hoop measuring attachment for cutting and punching machines comprising an annulus split and having its end portions attached to the machine and an adjustable barrel hoop engaging member on the band, said adjustable member comprising a hook, said band having a longitudinally extending slot'therein for receiving the shank portion of the hook and a nut on the shank portion of the hook adapted to be threaded inwardly to bind against the band and secure the hook against self adjusting.

5. A barrel hoop measuring attachment for cutting and punching machines comprising an annulus split and having its end portions attached to the machine and an adjustable barrel hoop engaging member on the band, and guide lugs on the band.
